I recently found out a simple crash in Windows Live Movie Maker 2011 Build 15.4.53508.1109

I have tested on Windows 7 Professional 32-bit SP1

I used a header of another .wav file and added random bytes inside the file. The application accepts our specially crafted .wav file when we try to import a music file to our project and causes a crash.

How can I report my exploit code?

This is not a exploitable vulnerability just a simple crash.
